I felt what I presumed to be Dave opening my arse out. I envisaged what it must look like and to see the other guy who I knew was now wankiing hard at...my sex orifice. I felt the first shot actually go across my buttocks. The second shot slowly oozed out of the wide pink slit in his bell end. He aimed it perfectly at the outstretched hole. Blob after blob oozed out.. The hole was now full of thick white cream. Absolutely full to the brim. As Dave let go, the hot sex opening closed slowly. She seemed to know more about this changing thing than he did and Stephen was fine to let her lead.This time Stephen had a few surprises for Stephanie, though. Yes, that was her name: Stephanie. He sometimes wondered what she looked like, but pictures were against the "rules". The rules were Stephanie's rules, but he obeyed them. He had felt the embarrassment before when he forgot one of the rules once. It was really just a casual thing: no one in the room on the night of the change. He forgot. .. how thoughtful of him! I stepped out of the loo to find Sue, one of the other shop assistants leaning against the counter. I looked her in the eye and there was no denying what I had been doing. "Hmmm" she began, "did you enjoy yourself in there, Kay?" I could only nod and smile.I hadn’t managed to put my jacket back on or do up the last few buttons on my shirt.She could clearly see my nipple rings and my tattoo….. I instantly remembered my promise to the boys.She smiled and stepped in. A shortriding crop in her right hand guarantees it. She's partially undoneher white blouse, just enough to tease you with glimpses of hersmall, round breasts tipped with pink nipples that reach out to youlike tiny fingers, rigid with the hope that you will misbehave, andshe'll get to use the crop on your smooth legs and belly. So you stop struggling, pulling your bare thighs togetherand to the side to avoid the crop, should it fall.? But you're still breathing hard, eyes full of.
